For each network element:

1. Water Ownership - pre-timestep calculations
2. Off Allocation: Generate additional release requests
3. The wetland cluster that the element belongs to is solved for this time-step.
4. Execute element flow phase calculations
5. Water Ownership - post-timestep calculations, and colouring of water
6. Calculate Constraint Factors for element
7. Constituent modeling is executed.

Generate Additional Release Requests

The off-allocation impact on the desired release down each outlet of the storage is calculated in the flow phase. For this reason, an extra calculation is undertaken (called the pre-flow phase), which informs the storage of any extra releases that need to be made to satisfy the off-allocation requests further downstream. Refer to Off Allocation node.

Ownership

Once the flow calculations have been completed for a node or link, an extra process needs to be completed which assigns a percentage of the total flow to each owner. There are occasions when the node or link needs to collect data before the flow is calculated at the network element, hence the extra step before the flow calculations. Refer to Ownership.

Constraint Factors

Every link and node contains constraint factors (referred to as the flow to order ratio) which is used to diagnose shortfalls in the system. These shortfalls are used by some nodes to redistribute future order. Refer to constraint factors under rules-based ordering (Ordering).
